cd /usr/src wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz
Now extract the downloaded package.
tar xzf Python-3.7.4.tgz
Step 3 – Install Python 3.7
Use below set of commands to compile Python source code on your system using altinstall.
cd Python-3.7.4 ./configure --enable-optimizations make altinstall

HI Rahul,
We do already have Py3.6.5 which was installed through Anancond. Now we need Py3.7.1 so I’ve installed Py3.7.1 using the above steps . It seems like it got installed by python3 -V still showing 3.6.5 only, not 3.7.1.
Can you help?
Succesfully Installed 3.7, but when i check version it is showing 2.7
I tried python3 -V, but it is showing ” python3: command not found”.
Below are the message after completing altinstall
“setuptools in /usr/local/lib/python3.7/site-packages (40.8.0)”
” pip in /usr/local/lib/python3.7/site-packages (19.0.3)”.
